Question 1956 ford car. The vacuum lines coming from fuel pump which goes to the carb. and which goes to window shell wipers
Answer The easiest way to tell is to start the engine with the lines off. Hold your finger over one and it will either have vacuum or be delivering pressure. If it is vacuum that is the one for the wipers and if it is pressure that goes to the intake manifold/carburetor.
